The Two Roll Refineris built with the latest technology and can serve either as a pre-finer before a five-roll refiner or as a standalone refiner for multiple refining steps. By crushing chocolate ingredients between two grinding rolls, it allows the use of crystal sugar instead of powdered sugar, which helps remove moisture from the chocolate.
As a pre-refiner, it reduces the particle size of the prepared mix from 600–1000 microns down to 80–130 microns. This process creates a strong bond between the raw material’s molecules and oils, improving adhesion to the refiner cylinders. It also shortens the conching time and thins the product using a compact hydrostatic pressure system. The capacity ranges from 10 to 60 kg per hour.
